Urm, it is probably /etc/mozilla-firefox in Sarge, and /etc/firefox in testing, since that is what the respective packages are called.

It may well be /etc/iceweasel in Etch when it is released but that is another battle entirely.

I would have expected new desktop deployments to be working with testing, but at this point there is probably no "immediate win" situation. Sarge is rather dated as a desktop (although use of backports might help).

If you need kool homepages, go to a site called http://www.eziner.info You can choose from 100's of themes to save as a homepage! I personally went with the Fish Tank... You can also find out how to change it there!
